Distributions of mRNA (yEGFP) counts per cell. (A) Overlaying the distributions for PTEF1(L0) and PTEF1(M3) reveals no significant effect of inserting the M3 stem–loop structure into the 5΄UTR. Panels B and C show the corresponding data for PPAB1(L0) and PDCD1(L0), respectively. (D) Overview of the data shown in A–C. The key statistical data are summarized in Table 1. The data obtained with the PTEF1 and PPAB1 promoters fit to negative binomial distributions (A, B). In the case of PDCD1(C), it is difficult to distinguish between negative binomial and Poissonian fits.
